Pediatric Surgery Lab
Machine-translated · View original
The lab supports children with diseases that require surgery through both clinical care and research.

AboutAbout the lab
With joy and pride, for the smallest patients.
As the pediatric surgery group within the Department of General Surgery at Tohoku University Hospital, the lab provides clinical care and conducts research for babies and children with diseases that require surgery.
It is a clinical department specializing in surgical diseases of the whole body in children, excluding the intracranial region, the heart, and the bones.
Its research focuses on biliary atresia, small bowel transplantation, intestinal failure, and childhood cancer.
The lab also works on minimally invasive surgery, which places less burden on patients, and on psychological support for patients and their families.
Key terms
- Biliary atresia
- A disease in which the bile ducts that carry bile made in the liver to the intestine become blocked, damaged, or lost. It develops in newborns and early infancy.
- Kasai procedure
- Hepatic portoenterostomy for biliary atresia. It is still regarded as the standard operation today.
- Intestinal failure
- A condition, caused by impaired intestinal motility or extensive resection of the intestine (short bowel syndrome), that often requires long-term intravenous nutrition.

ResearchResearch themes
While providing clinical care for surgical diseases from the newborn period through childhood, the lab conducts research to improve treatment. Its subjects include biliary atresia, small bowel transplantation, intestinal failure, and childhood cancer.
*Illustrative imagePathophysiology, diagnosis, and treatment of biliary atresia
This is a disease of newborns and early infancy in which bile can no longer drain from the liver into the intestine. The Kasai procedure (hepatic portoenterostomy), performed in the past by the late Professor Emeritus Morio Kasai, is still the standard operation today. The lab conducts research on the pathophysiology, diagnosis, and treatment of the disease.
*Illustrative imageImproving outcomes of small bowel transplantation
Mainly in Europe and the United States, small bowel transplantation is becoming established as a standard treatment for intestinal failure. This institution performs the most small bowel transplants in Japan, and conducts both clinical and basic research to improve treatment outcomes.
*Illustrative imageTreatment of intestinal failure and intestinal rehabilitation
Intestinal failure is a condition that often requires long-term intravenous nutrition. As one of the few facilities in Japan that run an intestinal rehabilitation program, the lab works with other departments and multiple professions on treatment and research.
*Illustrative imageClinical care and research on childhood cancer
At Tohoku University Hospital, which is designated as a core hospital for childhood cancer, the lab provides clinical care and conducts research in cooperation with the pediatric hematology-oncology group. Cases also come from across the Tohoku region.
